I purchased this based on the reviews, as well as the audio out and the included cable, as I needed to play along with some rehearsal material on my laptop. Now I need to buy another one because....

I was in the closed garage where I live during my lunch break ( I work from home) and within 2 hours it was stolen. Evidently, somebody else wanted it badly enough, because they left more expensive power tools and music gear around it. :s Go HARTKE!

The Hartke HD25 is a compact but powerful practice amp. It puts out 25 watts of power and has a nice warm tone. The built-in EQ system allows you to shape your sound for added versatility.

The auxiliary jack allows you to play over your music of choice and the headphone jack allows you to play and practice in silence. A great value for anyone who wants to get a small bass amp for either practice or small-venue gigs.

The HD25 is a great compact practice amp. It is an improvement from Hartke's BA series bass combos in that they updated the speaker to their Hydrive cone. The combination of paper and aluminum provides both warmth and punch at the same time. This amp is ideal for a bass practice amp as it provides just enough power to make some noise without angering others in your house. If you need to be quieter, the headphone jack will allow for private practice. The auxiliary jack will allow you to hook up your mp3 player or phone so you can learn your favorite tunes. The quality of tone and price point of this amp makes it a great value for any bass player looking for a nice practice amp.

The Hartke HD25 is a sleek durable bass combo amp that puts out 25 watts of power. It has a convenient mini plug input to connect any MP3 device to play along to. 8 " speaker which makes this amp ideal for practice. This is a real hands-on review from David @ Sam Ash Ontario.

This amp is great for multiple applications. Fantastic for bedroom practice. The hybrid paper/aluminum speaker cone lends itself to those seeking a fairly modern/contemporary tone. Built like a Hartke- solid. 8" speaker handles all frequencies with clarity and articulation. Great for both active and passive electronics. Do yourself a favor- buy a Hartke.

I really like the new hartke hd25. The controls are smooth and the amp is solid as a rock. Great sound out of this little 8 inch speaker. A must have for any bedroom or where a small amp is needed. I am a staff reviewer at Sam Ash Music.

This amp is great for practice, very clear tone, durable, and long lasting. The Hybrid speaker material ensures long speaker life, while also brining out sweet high end. This review is by a sam ash associate @ Cincinnati.

I was very surprised when I first tried this guy out! This is a great, loud, and clear little practice amp! With the aux in and headphone jack you can play quietly, or with the nice aluminum cone, you can really pump some air! Very loud for the size, but not loud enough to play with more than one other person! I love this little amp though!

If you need something in your room to jam your bass on, this is a great, inexpensive choice. It's got enough wattage to reproduce the bass frequencies that make you low notes sound good, or you can plug in headphones and silently plunk away. It doesn't have the umph to compete with a live drummer, but you could play with almost any other arrangement without straining the amp.
